[0063]如图3A所示,图3A是波长转换层203出射光的时序图的一种实施例。 [0063] As shown in FIG. 3A, FIG. 3A is a timing chart showing a wavelength conversion layer 203 emitted light embodiment. 在本实施例中,波长转换层203上的第一分区占270度,第二分区占90度。 In the present embodiment, the first partition on the wavelength conversion layer 203 accounted for 270 degrees, the second partition of 90 °. 从波长转换层203的第二分区开始进入激发光的入射光路开始,在波长转换层203转动的一周期T时间内,光源系统的工作过程如下。 The excitation light entered the incident light path from the wavelength conversion layer of the second partition 203 is started, the wavelength conversion layer 203 in a rotation period of time T, the light source system working process is as follows. 在前0.25T内,波长转换层203出射蓝光,在后0.75T内,波长转换层203出射黄光。 0.25T within the first wavelength conversion layer 203 emitting blue light, 0.75T in the wavelength conversion layer 203 emitted yellow light. 相对应地,前0.25T内DMD 211用于调制蓝光,DMD 213未用于调制光束。 Correspondingly, the front 0.25T DMD 211 for modulating blue light, DMD 213 is not used to modulate the light beam. 后0.75T内DMD211用于调制绿光,DMD 213用于调制红光。 After the DMD211 0.75T for modulating green light, DMD 213 for modulating red light. 如图3B和图3C所示,图3B和图3C分别为DMD 211和DMD 213对不同色光的调制时间图的一种实施例。 3B and 3C, 3B and 3C are modulated embodiment is a time chart DMD 211 and the DMD 213 different shade. 在这种情况下,每一个周期T内红光和绿光均全被利用,使得光源的利用最高效。 In this case, a period T of each red and green have all been utilized, such that the most efficient use of light. 然而,这可能不是实际情况,因为这可能引起该三基色光混合而成的白光的色坐标与预定色坐标有偏差。 However, this may not be the case as this may cause the color coordinates of the three primary colors and white light obtained by mixing a predetermined color coordinate deviation. 在实际运用中,可以通过利用该两个DMD对不同颜色光的调制时间的长短来控制白光的色坐标使之达到满意。 In practical use, by using the color coordinates of the two modulated DMD length of time for different colors of light is controlled so as to achieve satisfactory white light. 例如,在本实施例中,如果红光过多而导致白光的色坐标偏红,则可以控制DMD 213的调制时间变短,使得在一定时间段上的红光为无效光。 For example, in this embodiment, if the red light caused by excessive reddish color coordinate of white light, the DMD 213 can control the modulation time is shortened, so that the red light over a certain period of time in light of the present embodiment as invalid. 如图4所示,图4是DMD 213对红光的调制时间图的又一种实施例。 4, FIG. 4 is a further embodiment of DMD 213 to red light modulated according to a time chart. 在图4中,每一个周期T内红光的后段部分被舍弃。 In FIG. 4, a rear portion of each cycle period T in the red are discarded. 在实际运用中,也可以将红光的前段舍弃,或者中间的一端或几段舍弃,这都是容易理解的。 In practical applications, it may be discarded red anterior, intermediate or discard one or several sections, which are readily understood.

[0115]以上实施例中都是利用光波长的差异,使用滤光片或者滤光膜对光束进行透射和反射来进行分光或者合光。 [0115] the above embodiment is the use of a difference in light wavelength filter film or filter used for transmission and reflection of the light beam to the optical beam splitter or combined. 而某一个光路上的光在一个分光滤光片上被透射还是被反射,是可以任意设计的。 And a light path of a light is transmitted or is reflected on a dichroic filter, can be arbitrarily designed. 因此,在本发明的所有实施例中,各光路上不同波长范围光通过滤光片或滤光膜的具体的光学结构,都是为了方便说明而列举的例子,并不限制使用其它的利用分光滤光片或滤光膜进行光路合并或光束分光的光学结构。 Thus, in all embodiments of the present invention, examples of various wavelength ranges specific optical path of light through an optical filter film or filter structures, are exemplified for convenience of explanation and do not limit the use of other spectroscopic using an optical filter or a filter film or a combined structure of an optical path of a beam splitter.

[0131] 具体来说,第一发光器件为黄光LED 11a,第二发光器件为蓝光LED 11b,分别用于产生黄光和蓝光。 [0131] Specifically, the first light emitting device is a yellow LED 11a, the second light emitting device is a blue LED 11b, respectively, for generating yellow and blue. 第一控制装置用于分别控制不同颜色的发光器件的开启与关闭,使蓝光LEDllb和黄光LEDlla交替点亮,以产生时序的黄光和蓝光。 A first control means for respectively controlling on and off the light emitting devices of different colors, so the blue light and yellow light LEDlla LEDllb alternately illuminate, to generate timing yellow and blue.

[0132] 在本实施例中,在某一时段第一控制装置可以控制黄光LEDl Ia和蓝光LEDlIb同时点亮。 [0132] In the present embodiment, a certain period of the first control means may control the yellow and blue LEDlIb LEDl Ia lit simultaneously. 由于蓝光以及黄光分光后得到的绿光均在DMD 1611中进行调制,则在黄光LEDlla和蓝光LEDllb同时点亮的这个时间段中,DMD1611用于对蓝光和绿光的合光即青色光进行调制,对于DMD 1613则没有影响。 Since the blue and the green spectral yellow light obtained in the DMD 1611 are modulated in the blue light and the yellow light LEDlla lit simultaneously LEDllb this time, DMD1611 for light combination of blue and green light, i.e., cyan modulated, for DMD 1613 is not affected. 在这个时间段中,由于两种光的混合,使得DMD 1611能够调制多一种颜色,使得该DMD 1611能够调制的色域更大。 In this period, since the mixing of the two light modulation such DMD 1611 can be multi-color, so that a larger color gamut of the DMD 1611 can be modulated.

[0133]如图17A所示,图17A为光源系统1600出射光的颜色时序图。 [0133] As shown in FIG. 17A, 17A is a timing chart of a light source system 1600 color emitted light. 在一个周期T内,在tl时间内,点亮蓝光LED,则发光装置I出射蓝光;在t2时间内,点亮黄光LED,则发光装置I出射黄光;在七3时间内,同时点亮蓝光LED和黄光LED,则发光装置I出射该两种光的合光,即白光。 In a period T, in the time tl, the LED is lit blue, the emitted blue light emitting device I; in the time t2, the LED is lit yellow light, the yellow light emitting device emitted I; 3 in seven time and point bright blue LED and a yellow LED, the light emitting device of the light I emitted combined two lights, i.e., white light. 如图17B和图17C所示,图17B和图17C分别为DMD1611和DMD1613对不同色光的调制时间图。 As shown in FIG. 17C and FIG. 17B, 17B, and 17C are modulated DMD1611 DMD1613 time and different shade of FIG. 相对应地,tl时间内DMD 1611用于调制蓝光,DMD1613未工作;t2时间内DMD1611用于调制绿光,DMD1613用于调制红光;t3时间内,DMD1611用于调制青光,DMD1613用于调制红光。 Correspondingly, the time tl for modulating blue DMD 1611, DMD1613 is not working; DMD1611 period t2 for modulating green light, DMD1613 for modulating red light; the time t3, for modulating DMD1611 glaucoma, DMD1613 for modulating red.

[0134]但是,不能一直使该两种颜色光同时点亮,由于本光源系统中只有两个DMD,其中一个DMD用于在不同的时段分别调制蓝光和绿光。 [0134] However, not always that the two kinds of color light lit simultaneously, since the present system has only two DMD light source, wherein a DMD for different periods respectively modulate blue and green. 如果黄光LEDlla和蓝光LEDllb—直保持同时点亮,则导致没有蓝光和绿光这两种单色光图像,而只有青色光的图像。 If the yellow and blue LEDllb- straight LEDlla are kept lit, blue and green light resulting in no two monochromatic image, but only the image of the blue light.

[0135]容易理解的是,如果分光系统2中的滤光片1609用于透射红光并反射绿光,则蓝光和黄光分光后得到的红光均在DMD 1611中进行调制,绿光在DMD 1613中进行调制。 [0135] readily understood that, if the filter 2 for splitting system 1609 reflects the green light and transmits red, blue and yellow are obtained after the spectroscopic are modulated in red DMD 1611, the green light DMD 1613 are modulated. 则在黄光LED 11 a和蓝光LED 11 b同时点亮的这个时间段中,该DMD 1611用于对蓝光和红光的合光即紫色光进行调制,对于DMD 1613则没有影响。 Then the yellow LED 11 a blue LED 11 b and lit simultaneously this time, the DMD 1611 for the blue and red light combiner i.e. violet light is modulated, for DMD 1613 is not affected.

[0136]相比以上实施例,本实施例能同时点亮不同颜色的发光器件,使得用于调制的颜色光更多,进而能够调制的色域更大。 [0136] As compared to Example above, the present embodiment can simultaneously lighting the light emitting devices with different colors, so that the color modulated light for more and larger color gamut and thus can be modulated.

[0161]本实施例中,也可以在一个调制周期T内加入时间段t4,在该时间内,三个光源同时点亮,则两个DMD用于调制蓝光和黄光的合光,即白光。 [0161] In this embodiment, the time period t4 can be added in one modulation period T, at which time the three light simultaneously, the two DMD for modulating light combination of blue and yellow, i.e., white . 这样,可以提高光源系统的亮度。 Thus, the system can increase the brightness of the light source. 在本实施例中,tl、t2、t3和t4的比例可以根据对不同颜色的实际比例需要来进行调整。 In the present embodiment, tl, t2, t3 and t4 may be based on the ratio of the actual proportions of the different colors need to be adjusted.

[0162]相比以上实施例,本实施例中可通过分别控制两个黄光光源的亮度来分别对两个DMD接收到的红光和绿光的亮度进行调整,并且减少了对滤光装置驱动的第二驱动装置的使用;同时,由于光源的点亮不需与滤光装置的转动相同步,在控制不同光源的时序点亮上更加容易,在调整DMD对不同颜色光调制的量也更加方便。 [0162] As compared to Example above, the luminance of red and green in the embodiment may be respectively received by two DMD control two yellow light source brightness adjustment of the present embodiment, and reduces the filtering means a second driving device is driven; the same time, since the rotation of the lighting device without the light source and the filter is synchronized, easier to control different light sources in the lighting sequence, DMD also adjusting the amount of modulation of different colors More convenient.

[0163]容易理解的是,本实施例中的其中一个黄光光源也可以替换成第三颜色的发光元件。 [0163] readily understood that the present embodiment wherein a yellow light source to the light emitting element may be replaced with a third color. 相对应的,用于分光的滤光片2405的滤光曲线同时还设置为透射第三颜色光的一个波长范围的光并反射第三颜色光的另一波长范围光。 Correspondingly, for the spectral filter curves of the filters 2405 and also to a wavelength range of light transmittance of the third color light and reflects a third color light to another wavelength range of light.

[0164]在本实施例中,发光装置中还可以通过激发光激发转动的色轮而产生三束时序光,而分光系统中也可以通过与色轮同时转动的滤光轮来对该三束时序光进行分光来实现。 [0164] In the present embodiment, the light emitting device may also be three beams generated by light excitation timing of the color wheel rotates excitation light, and the spectroscopic system may be the three beams by the color wheel while rotating the filter wheel The timing light disperses to achieve. 以上实施例已经对这些装置进行描述,只需简单的对不同实施例中的发光装置和分光系统进行组合即可,在此不再赘述。 The above embodiments have been described with these devices, simply different embodiments of the light emitting device and a spectroscopic system can be combined, omitted here.

[0177]本实施例与图24所示实施例的区别之处包括: The embodiment differs from the embodiment shown in Fig EXAMPLE 24 [0177] This comprises:

[0178]图24所示的光源系统中发光装置通过时序点亮四个光源来产生时序光,而本实施例中的发光装置采用色轮结合时序点亮光源两种方式来产生时序光,具体说明如下。 The light source system shown in [0178] FIG. 24 the light emitting device generates light through the timing sequence four lighting source, and a light emitting device in the present embodiment is employed in conjunction with a color wheel timing the light source to generate a sequence of light in two ways, particularly described as follows.

[0179] 波长转换层2805上包括第一分区2805A、第二分区2805B、第三分区2805C和第四分区2805C,分别设置有第一、第二、第三和第四功能材料,分别用于吸收激发光并产生第一、第二、第三、第四光。 Comprising [0179] a first wavelength conversion layer 2805 2805A partition, the second partition 2805B, 2805C third partition and a fourth partition 2805C, are provided with a first, second, third and fourth functional material, respectively, for absorbing excitation light and generating a first, a second, a third, a fourth light. 在本实施例中,两个激发光源均为UV光,第一和第三分区上均设置有黄光波长转换材料,第二和第四分区上均设置有蓝光波长转换材料。 In the present embodiment, two excitation light sources are UV light, the first and third partition is provided with a wavelength conversion material is yellow light, blue light is provided with a wavelength converting material on the second and fourth partition. 在同一时间段内第一分区和第三分区分别位于两个激发光源产生的激发光的出射光路上,另一时间段内第二分区和第四分区分别位于两个激发光源产生的激发光的出射光路上。 In the same period of the first partition and the third partition are located at two excitation light path of the outgoing light of the light produced by the excitation, the other fourth period of the second partition and two partitions are located in the excitation of the light produced by the excitation light outgoing path.

[0180]第一驱动装置2806用于驱动波长转换层2805,使得激发光在波长转换层2805上形成的光斑按预定路径作用于该波长转换层2805。 [0180] The first driving means 2806 for driving the wavelength conversion layer 2805, so that the excitation light spot in a predetermined path to act on the light wavelength conversion layer 2805 is formed on the wavelength conversion layer 2805. 同时,第一控制装置用于控制两个激发光源,使得当第一分区2805A和第三分区2805C位于两束激发光的光路上时的至少部分时段交替点亮,当第二分区2805B和第四分区280f5D位于两束激发光的光路上时至少部分时段同时点壳。 Meanwhile, a first control means for controlling the two excitation light sources, such that at least a part of a period when the first partition and the third partition 2805A 2805C located in the optical path of the two beams alternately illuminate excitation light, when the second and the fourth partition 2805B 280f5D partition positioned on the optical path of the excitation light beams of at least two part shells time point simultaneously.

[0181]以下具体举例来说明。 [0181] The following specific examples will be described. 如图29所示,图29是图28所示的光源系统中的波长转换层的主视图的一个实施例。 29, FIG. 29 is a front view of the embodiment of the wavelength conversion layer, the light source system shown in FIG. 28 in Fig. 在本实施例中,波长转换层2805呈圆盘状,且第一分区2805A和第三分区2805C呈180度设置,第二分区2805B和第四分区2805D呈180度设置。 Embodiment, the wavelength conversion layer 2805 has a disk shape in the present embodiment, the first section 2805A and 2805C and the third partition 180 degrees is provided, the second partition 2805B and 2805D fourth partition disposed 180 degrees. 第一驱动装置280为马达,用于驱动波长转换层周期性转动。 The first driving means 280 is a motor for driving the rotation of the wavelength conversion layer periodically. 两束激发光在波长转换层2805上各自形成的光斑的连线经过圆盘的圆心,使得在同一时间内呈180度设置的分区分别位于该两个激发光源产生的激发光的出射光路上。 Two light beams in the excitation wavelength conversion wiring layer 2805 formed on each spot passes through the center of the disc, such as a partition are located 180 degrees of the two excitation light path of the outgoing light produced by the excitation light at the same time.

[0182]在本实施例中,波长转换层2805设置为反射式的,即激发光与受激光的光路位于该波长转换层2805的同一侧。 [0182] In the present embodiment, the wavelength conversion layer 2805 is a reflection type is provided, i.e., the optical path of the excitation light and receiving the laser beam on the same side of the wavelength conversion layer 2805. 可通过在波长转换层2805背向激发光源的一侧放置反射镜或者镀有反射膜来实现,此为公知技术,在此不再赘述。 Can be prepared by known techniques excitation wavelength conversion layer 2805 is placed away from the mirror to the light source or plated to achieve a reflective film, this is, are not repeated here.

[0184]分光系统用于将第一光和第三光分别分成沿第一光通道和第二光通道出射的两束不同波长范围光,并分别沿第一光通道和第二光通道出射第二光和第四光。 [0184] spectroscopic system for the first light into a third light, respectively, along a first optical path and the two beams of different wavelength range of light emitted tells the second light flux, and respectively along a first optical path and the second light flux emitted tells of two light and the fourth light. 在本实施例中,反射镜2812位于第二受激光的出射光路上,第一受激光和经反射镜2812反射的第二受激光分别入射至滤光片2811的两侧。 In the present embodiment, the mirror 2812 is in the second outgoing path converted light, receiving the first and second laser beam reflected by the laser reflection mirror 2812 are incident on both sides of the filter 2811. 滤光片2814用于反射黄光(即第一光和第三光)中的绿光成分并透射红光成分,还用于反射蓝光(即第二光和第四光)沿第一光通道和第二光通道出射。 2814 filter for a green component reflected yellow light (i.e., the first light and the third light) and transmits light in the red light component is further configured to reflect blue light (i.e., a second light and the fourth light) along a first optical path and tells the second light flux emitted. DMD 2811用于对经滤光片2814沿第一光通道出射的光束进行调制。 DMD 2811 through the filter 2814 for a first light flux emitted tells beam modulation. DMD 2813用于对经滤光片2814沿第二光通道出射的光束进行调制。 For DMD 2813 via the filter 2814 along the second light flux emitted tells beam modulation.

[0185]优选地,第一受激光经反射罩2803收集后依次进入匀光装置2807匀光和收集透镜2810后再出射至滤光片2814。 [0185] Preferably, the first laser beam reflected by the cover 2803 collected into the light homogenizing unit 2807 sequentially uniform light collection lens 2810 to filter 2814 and then exit. 同样的,第二受激光经反射罩2804收集后依次进入匀光装置2808匀光和收集透镜2809后再出射至滤光片2814。 Similarly, the second laser beam reflected by the cover in order to enter the light homogenizing apparatus 2808 2804 collection uniform light collection lens 2809 to filter 2814 and then exit. 这样,能提高第一受激光和第二受激光的利用率,减少光损失。 Thus, the laser can be improved by the first and second laser efficiency by reducing light loss.
